IsSubpictureStreamEnabled Method

Show in webframe
Example 



Leadtools.Multimedia Namespace > DVDControl Class : IsSubpictureStreamEnabled Method
The Subpicture stream to check.
Gets the current title's specified Subpicture stream enabled state.
Syntax
'Declaration
 
Public Function IsSubpictureStreamEnabled( _
   ByVal Stream As Integer _
) As Boolean
'Usage
 
Dim instance As DVDControl
Dim Stream As Integer
Dim value As Boolean
 
value = instance.IsSubpictureStreamEnabled(Stream)
public bool IsSubpictureStreamEnabled( 
   int Stream
)
public:
bool IsSubpictureStreamEnabled( 
   int Stream
)

Parameters

Stream
The Subpicture stream to check.

Return Value

true if the Subpicture stream is enabled; false, otherwise.
Remarks
The SubpictureStreamsAvailable property contains the number of available Subpicture streams. The CurrentSubpictureStream property contains the current Subpicture stream. The title currently being played determines which Subpicture streams are enabled and disabled. While setting a disabled Subpicture stream as the current Subpicture stream will not return an error, the program will not display Subpicture data until it plays a title that enables the stream.

For more detailed information, refer to the Microsoft documentation for IDvdInfo2.IsSubpictureStreamEnabled.
